Demand for Gemini Telescope Time

Demand for Gemini Telescope Time

The figures below show the total demand in hours from each partner, host institution and staff, as well as the summed demand. From 13A the UK is no longer a
partner. Requests for
Exchange time are not included.
The ratio of the total demand to the time available is given in the
Over-Subscription page.
Note that the requested time does not include time required for calibrations, unless the calibrations are non-standard.
The
Observing Overheads page
summarises all overheads associated with Gemini observations.
The standard, baseline, calibrations are described on
the GMOS Baseline Calibrations webpage, the NIR Baseline Calibrations webpage, and the Mid-IR Baseline Calibrations webpage. Telescope time used in program calibration varies by instrument. For GMOS, calibrations add about 5% to the program time, for NIRI 10%. for GNIRS and NIFS 23%. For the typical instrument distribution across the sites, the additional overhead due to calibrations is 9% for Gemini North, and 5% for Gemini South.
